Bumper pool game with impact responsive actuation-deactuation structure for marking and unmarking of selected bumper elements

ABSTRACT

Game apparatus comprises a plurality of targets, disposed on a playing surface, and marking circuitry coupled to light bulbs associated with the targets. The marking circuitry is actuable upon the closing of normally open switches to mark at least one target to be distinguishable from other targets, until that target is struck by a striking element movable upon the playing surface. Marking selection structure in the form of a movable programmer member controls the sequence of marking of targets and includes an array of cam elements for closing the marking circuit switches. The position of each cam element on the programmer member determines to which target marking circuit the cam relates and at what point in the target marking sequence such relating occurs. Each target includes a flexible contact member which, upon collision of a striking element with the target, flexes to connect electrically with a selection circuit contact, thereby closing a switch in a selection circuit. The selection circuit is coupled to a solenoid having a movable armature biased to engage a ratchet mechanism, associated with the programmer member, to prevent motion of the latter member. Closing of the selection circuit switch after collision of a striking element with a marked target results in a disengagement of the armature from the ratchet mechanism, thus permitting incremental motion of the programmer member under the influence of a power source coupled thereto, until a cam element on the programmer member causes closing of a marker circuit; a contact associated with the programmer member cam element concurrently disengages to open a solenoid switch in the selection circuit and deactivates the solenoid, thereby engaging the solenoid armature with the ratchet mechanism. The cycle is repeated until the game is over. In apparatus with depletable power source, such as a windable power spring coupled to the programmer member, a warning indicator coupled to a warning circuit is actuated by a warning circuit cam element, disposed upon the programmer member, which closes a warning switch.

The marking circuitry is actuable upon the closing of normally open switches to mark at least one target to be distinguishable from other targets, until that target is struck by a striking element movable upon the playing surface. Marking selection structure in the form of a movable programmer member controls the sequence of marking of targets and includes an array of cam elements for closing the marking circuit switches. The position of each cam element on the programmer member determines to which target marking circuit the cam relates and at what point in the target marking sequence such relating occurs. Each target includes a flexible contact member which, upon collision of a striking element with the target, flexes to' connect electrically with a selection circuit contact, thereby closing a switch in a selection circuit. The selection circuit is coupled to a solenoid having a movable armature biased to engage a ratchet mechanism, associated with the programmer member, to prevent motion of the latter member. Closing of the selection circuit switch after collision of a striking element with a marked target results in a disengagement of the armature from the ratchet mechanism, thus permitting incremental motion of the programmer member under the influence of a power source coupled thereto, until a cam element on the programmer member causes closing of a marker circuit; a contact associated with the programmer member cam element concurrently disengages to open a solenoid switch in the selection circuit and deactivates the solenoid, thereby engaging the solenoid armature with the ratchet mechanism. The cycle is repeated until the game is over. In apparatus with depletable power source, such as a windable power spring coupled to the programmer member, a warning indicator coupled to a warning circuit is actuated by a warning circuit cam element, disposed upon the programmer member, which closes a warning switch.

21 Claims, 9 Drawing Figures PATENTED DECS 1 I974 SHEET 30F 3 I BUMPER POOL GAME WITH IMPACT RESPONSIVE ACTUATION-DEACTUATION STRUCTURE FOR MARKING AND UNMARKING OF SELECTED BUMPER ELEMENTS A game method includes disposing a plurality of targets upon a playing surface and marking the targets for striking by a striking element, which may take the form of a ball rollable upon the surface. After a target is struck, the. next target for striking is marked. Marking may be in a sequence which is calculated to give the im pression of randomness, thus preventing a player from calculating his shot at a marked target so that the striking element will be appropriately positioned for striking the next marked target.

BACKGROUND OF THE INVENTION The invention relates to apparatus and methods for games in which an objective is to strike targets.

One of the most popular recreational activities for young and old has comprised striking a ball or other movable object with hand held means to cause the movable object to strike a target. Games such as pool, billiards, and snooker are examples of this activity. A particular form of this game concept has been in the game of bumper pool, which comprises a plurality of targets disposed on a table top surface, the rules requiring the targets to be struck in a predetermined se-v quence by a ball struck by a pool cue. Means included in the bumpers provide a highly elastic collision with the striking ball so that an element of unpredictability ofpositioning of the ball for the next stroke, aimed at the next bumper, is introduced.

In such bumper pool games, however, players possessing a reasonable degree of inherent coordination and having the. opportunity for reasonable practice of the game soon become so adept at the game that they, in effect, master the game so that they readily complete an entire sequence of impacts with the bumpers without interruption due to missing a bumper or being out of position to strike a bumper after striking the prior bumper in the sequence, thus denying the other player a chance to compete. This strongly diminishes the competitive aspect of the game.

Therefore, there has been a recognized, but unfulfilled need for a billiard type game including bumpers in which a substantial element of unpredictability regarding the sequence of bumpers to be struck is present.

A game apparatus includes game objective means, which may comprise target means, markable in a predetermined sequence to be distinguishable from other target means by marking means coupled to the target means. In a preferred embodiment, the marking means comprises circuit means including marking circuit switch means closable to effect marking of target means. Marking selection or programmer means comprises movable means positionable to close marking circuit switch means. Collision of a striking element with a marked target means displaces an impact responsive contact means to close switch means coupled in selection circuit means operatively associated with the movable means. The selection circuit means is operatively associated with the movable means to control motion thereof and, in a preferred embodiment, includes means for permitting motion thereof upon closing of the selection circuit means after impact of a striking element with a marked target means. Means coupled with the movable means are provided to open the selection circuit means upon motion ofthe movable means into position to close a marking circuit means. Drive means coupled to drive the movable means may comprise a depletable power source, and means may be provided to indicate the imminent depletion of the source.

FIG. 7 comprises a simplified view of means coacting with the means of FIG. 6; and

FIG. 8 comprises a schematic diagram of electrical circuit means for sequentially marking targets in accordance with the invention.

In a presently preferred embodiment of the invention, game apparatus 10 includes game objective means 12 in the form of target means 14. Preferably, as depicted, several target means 14 are employed. though any number of target means may be employed in accordance with the invention. Target means T4 are disposed to protrude above a playing surface 15, which-may be planar as shown. As depicted, the surface l5 may define holes or pockets I5 into which a ball may be directed. Scoring means 15 may be disposed as shown at the periphery of the playing surface I5.

'As shown in FIGS. 2 and 3, target means 14 includes means 16 for marking the target means 14 as distinguishable from other target means M. The marking may be, in the embodiment depicted, to designate a target as the next target to be struck, but in accordance with the invention may comprise means for designating game objects as objectives of game activity of a general type. For example, the marking means may be utilized to single out a particular element of a game for special attention or for special scoring potential.

Preferably, as depicted, marking is effected through electrical means (discussed in detail in conjunction with FIG. 8) mounted in conjunction with a target means I4; however, marking may be also effected by mechanical or electromechanical means and other mountingarrangements may be employed, in accordance with the invention. As described in detail below, marking, means I6 comprises electrical circuit means including switch means closable by coupling of first contact means 17 and second contact means 18, as described in detail below. The means T7, 18 are, as depicted, preferably mounted on target means M.

Marking selection or programmer means 20 includes game-event responsive means in the form of impact responsive means 22 including a contact ring 24, and a flexible member 26 at least partially supported by the contact ring 24.

Referring also to FIG. 4, the contact ring 24 preferably, as depicted, comprises a peripheral element 28 flexibly connected at flex points 30 to a plurality of contact fingers 32. The contact ring 24 is disposed about an axial member 33 of the target 14. Fixed contact means 34 is mounted adjacent fingers 32 upon a mounting element 35 resting upon surface 15. A resilient member 36 is mounted upon target 14 to extend substantially as far outward of the member 33 as the member 26. Disposed in the axial member 33 of target 14 is a marker 38 in the form of a bulb 40. Other markers, such as flags or other devices focusing attention,

may be employed in accordance with the invention. As described below in detail, the marker 40 is supported on an internal member 41 and is coupled to marking circuit means for actuating the marker to designate the target as an objective in the game.

As depicted in FIGS. 3 and 5, in operation, the striking element which may take the form of a ball 42 (shown in phantom) such as a billiard ball, collides with impact responsive means 22 causing flexible member 26 to deform. As shown, deformation or flexing of the member 26 (shown in dotted lines)is in the direction of axial member 33 of the target 14, at the impact point and in the vicinity thereof. Opposite to the area of impact, flexing is'directed outwardly and downwardly, toward fixed contact 34. This motion produces flexing (shown in dotted lines) of fingers 32 to contact the fixed contact 34. As described in detail below, this contact actuates selection means 20 for varying the marking ofthe target means 14 so that after the impact, another target becomes marked, or the struck target becomes remarked, in a preselected pattern which may be calculated to convey the impression of randomness in selection of marking. Concurrently with impact of the ball 42 with the means 26, the ball strikes resilient means 36 and is deflected away from the target 14. Because of the-apparent randomness of the marking pattern referred to above, the next target to be designated is not known prior to striking of the marked target and thus players cannot calculate their stroke to position the rebounded ball for accessibility to the next marked target. Thus, an interesting element of uncertainty is added to the game and produces substantially greater demands on the skill of the players than a conventional game in which the sequence of targets to be struck is known in advance.

The placement and configuration of the resilient element 36 and the impact responsive means 22 are such as will permit a soft impact to cause the responsive means 22 to flex appropriately and will protect the means 26 from damage due to excessively hard impacts.

As depicted in FIGS. 1, 2, 6, 6A, and 7, marking relation means 20 comprises movable marking selector or programmer member 46 disposed adjacent a contact assembly 47, including separate banks 47, 47" of contact means 17, 18, respectively, mounted upon an insulator member 47" attached to target means 14. Programmer member 46 comprises a wheel 48 mounted on target means 14. Wheel 48 need not be mounted on target 14 and is so depicted for clarity and because the depicted arrangement is advantageous with regard to manufacturing convenience. Programmer member 46 includes an array 50 of cam means 52 tivating a warning indicator. The connection of the contact means to appropriate circuitry is described in detail in conjunction with FIG. 8 below.

Means 52 are arrayed in different angular and radial locations. In the depicted arrangement, different radial positions correspond to different pairs of contacts in the assembly 47 and thus to marking of different target means. Different angular positions correspond to different positions in the sequence of target marking. Rotational motion of wheel 48 thus serves to implement a sequence of marking of target means. In accordance with the invention, the function of radial and angular placement may be reversed and non-rotational motion or a non-circular programmer may be utilized. Also, as explained in detail below, an element of true randomness in target selection may be introduced under certain circumstances thus providing an alternative to an entirely predetermined sequence of marked targets.

Wheel 48 is coupled to stepping means in the form of ratchet means 54 including teeth 56 arrayed so that there is, for every cam means 52, a tooth disposed on a radial line of the ratchet mechanism corresponding in angular orientation to the angular orientation of the radial line of the wheel 48 through the cam means 52. Brake or interruptor cam means 57 are disposed at the underside of wheel 48 so that a means 57 corresponds in angular position to every cam means 52. Means 57 is engagable to close a normally open switch in a circuit, described in detail below, coupled to brake or interruptor means which may take the form, as depicted, of a solenoid 58 having a movable armature 60. Armature 60 is biased outwardly to engage with ratchet teeth 56 to prevent motion of the wheel 48. Other arrangements, such as an escapement incorporating the solenoid armature 60 may be employed in accordance with the invention. An element of actual randomness may be introduced into the sequence of target of target marking by suitably varying the flight time of the armature 60.

Motive power means shown in the form of mechanical tension means comprising a spring 61 is coupled to the wheel 48 to provide motive power thereto. Other means comprising electrical or other types of motive means may be employed in accordance with the invention.

As shown in FIG. 8, circuit means in accordance with the invention includes selection loop means 62 coupled to the solenoid 58 and marking loop means 64 coupling to markers 40. Loop 62 comprises a source of EMF 66 and includes selection varying switch means 68 coupled to a gate of an SCR 70 in series with solenoid 58. Finger means 32 and contact means 34 comprise the elements of switch means 68. Normally closed solenoid switch 69 is connected in series at the input of SCR 70. Cam means 57 engage with switch means 69 to open the normally closed switch means. Loop 64 comprises marker means 40 coupled with power source 66 via switch means 72. Contacts 17, 18 comprise switch means 72. For each separate target means there are a loop 62 and a loop 64. Warning indicator means 73 comprises a loop of the type of loop 64 and includes switch means 72 including warning marker contacts 17', 18. The switch 73 isshown as spaced slightly apart from the circuit elements corresponding to marker 40 for clarity. lnseries with power means 66 is system on/- off switch 74. I

In operation, when a particular target 14 is marked, its switch 72 is closed by contact between contact means 17, 18 corresponding to that particular target, and current appears in the marker 40 associated with that target. Upon collision ofa striking element 42 with impact responsive means 22 of the marked target, finger means 32 contact contact means 34 and switch 68 is closed. As a result, the gate of SCR 70 is biased, and the SCR fires, conducting current through the solenoid 58. Consequently, the shaft 60 of the solenoid is retracted and the wheel 48 is permitted to turn until a cam means 57 opens the switch 69 and the SCR 70 resumes the off condition, causing the armature 60 to engage a tooth 56 of the wheel 48. In this position, contacts l7, 18 are coupled and switch 72 is closed illuminating the marker 40 of the target involved. This sequence continues until the end of the game or, in the embodiment depicted having a depletable power source, untilwheel 48 reaches the point at which cam 52 couples contacts l7, 18, to activate warning marker 73 indicating that the spring 61 has little or no mechanical energy remaining. In one embodiment, the spring 61 is configured to produce sufficient energy for one total rotation of the wheel 48 and thus after a 360 rotation contacts l7, l8 connect at the point of the motion cycle of wheel 48 at which remaining spring tension is small.

A method of playing a game may provide that the winner is the player who first strikes a prescribed number of marked targets, and that a player may continue.

his turn until he fails to strike a marked target. Other methods of play relating to marked targets may be employed in accordance with the invention.
